23 Getting Started Protect Your Instrument from Misuse Check Input and Output Connectors. The instrument has both input and output connectors on the front panel. When connecting a cable, be sure to distinguish the input connector from the output connectors. Output Do not mistake Output connectors for Input. Input The arbitrary/function generator input and output connectors are floating inputs/outputs. WARNING. To prevent electrical shocks, do not apply voltages in excess of 42 Vpk to any BNC connector ground or to the chassis ground. CAUTION. Do not short output pins or apply external voltages to Output connectors. The instrument may be damaged. CAUTION. Do not apply excessive inputs over +5 V to Trigger Input connector. The instrument may be damaged. Use Fuse Adapter The instrument will be damaged if a large DC or AC voltage is applied to the output or input connectors. To protect the output circuits, a fuse adapter is provided as an optional accessory. When the instrument is used by students or other inexperienced users, always attach the fuse adapter to the output connectors to avoid damage. Tektronix part numbers for the fuse adapter are as follows: : Adapter : 0.25 A fuse set (3 each) Adapter 0.25A Fuse AFG3000 Series Quick Start User Manual

24 Getting Started Floating Ground Since the common (input and output channel common) of the arbitrary/function generator is electrically isolated from the chassis ground (the instrument chassis and ground line of the AC connector), you can make a floating connection between the instrument and other equipment. All the signal output connectors are connected to the common ground, and the remote interface connector is connected to the chassis ground. CAUTION. When you make a floating connection, review the following precautions: The maximum rated voltage between the chassis ground and common ground is 42 V p-p (DC + peak AC). When the potential voltage between the chassis ground and common ground goes over 42 V p-p, the internal protective circuit will be activated to protect the circuits. However, higher voltage may cause the internal circuits in the instrument to be damaged. When a potential voltage exists between the chassis ground and common ground, a short circuit from output to ground causes the instrument internal fuse to open and the output is stopped. If the fuse opens, you need to contact your local Tektronix Service Support. When a potential voltage exists between the common ground and chassis ground, short-circuiting between them may lead to excessive current flow and the internal or external circuits may be damaged.

25 Getting Started Protect Your DUT Use care when you connect the instrument Channel Output to your DUT (device under test). To avoid damage to your DUT, the following preventive measures are provided. Follow these steps to set the limit values for high level and low level.. Push the front-panel Top Menu button. The Output Menu is displayed at the bottom of the bezel menu. Select Output Menu. 2. In this example, High Limit is set to V, and Low Limit is set to V Push the Limit bezel button. 4. Select High Limit. Use numeric keys or the general purpose knob to enter a value. Enter 50 mv for High Limit, and 50 mv for Low Limit Push the front-panel Sine button to display the waveform parameter. Confirm that High and Low voltage levels were changed. You cannot enter any values greater than 50 mv for High level. 5 Quick Tip When you set limit values using Output Menu, a level indicator is displayed at left end of graph area. Refer to Screen Interface on page 20 for the level indicator. AFG3000 Series Quick Start User Manual 3
